Android :understanding the download process -

-

I am trying to calculate my WiFi speed so I am downloading a file from a server (10 MB ). Well downloading is working very well. But I'm not sure how to press the downloads of every available data packet.

I am using a part of this code, I want to understand the difference between the two sizes: 8192 and 1024, pulp of every size. 

  inputstream input = new beefInputstream (url.openstream (), 8192);

and this line 

  byte data [] = new byte [1024];

And how I used them: 

  protected string doInBackground (string ... f_url) {int count; Int lenghtOfFile = 0; {URL url = Try new URL (f_url [0]); Comm = (HttpURL connection) url.openConnection (); URL Connection Connection = url.openConnection (); Conection.connect (); LenghtOfFile = conection.getContentLength (); // file inputstream input = new buffer inputstream (url.openstream (), 8192); // output stream output stream output = new file output stream ("/ sdcard / downloadedfile.jpg"); Byte data [] = new byte [1024]; Long total = 0; While ((count = input.read (data))! = -1) {actuaStartlTime = System.currentTimeMillis (); Total + = Calculation; }}

This is a sample of output: Curate the time and information downloaded. I do not see any relativity between the size of downloaded data.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the
